摘要

The energy spectra and angle-distribution of the X-ray photons produced through 180° Thomson scattering were studied by Monte Carlo numerical simulation code CAIN. The laser intensity and electron parameters required for high quality X-ray source were also explored. Results show that to get higher photon production and suppress the nonlinear scattering, the laser intensity should not be too high. To get a monochromatic and highly luminous X-ray source, the electrons should have quasi-monoenergetic energy distributions, high energy, small divergence and short pulse length.
